            Bug ID: 57791
           Summary: Tomcat 8 Resources doesn't work with Servlet 3.0
                    META-INF/resources
           Product: Tomcat 8
           Version: trunk
          Hardware: PC
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
          Assignee: dev@tomcat.apache.org
          Reporter: ilu...@gmail.com

Sample projects demonstrating the bug

In Tomcat 8 the Resources framework intented for loading JSP, static resources
and JAR, doesn't work with resources located in META-INF/resources as specified
by Servlet 3.0 specification.  In Tomcat 7 with the old VirtualWebLoader this
feature worked pretty well.

For example you have a JAR with this content

/META-INF/resources/admin/test.jsp
/META-INF/resources/admin/test.js
/META-INF/resources/tags/test.tag
/META-INF/tlds/javapp.tld 

Normally with Servlet 3.0 feature you can access this files for example:

http://localhost:8080/webapp/admin/test.jsp Doesn't work, 404 for you

Tag libraries declared in JARs including those linking to Tag files doesn't
work too
For example this Tag Library located at /META-INF/tlds/javapp.tld doesn't work

<taglib>
  <tlib-version>1.0</tlib-version>
  <short-name>javaapp</short-name>
  <uri>/javaapp</uri>
  <tag-file>
    <name>test</name>
    <path>/META-INF/tags/test.tag</path>
  </tag-file>
</taglib>


I tried with the following configurations in context.xml

This
<?xml version="1.0" encoding="UTF-8"?>
<Context  path="/webapp"  >   

    <Resources>

        <PostResources
className="org.apache.catalina.webresources.DirResourceSet"
                       base="D:/PROYECTOS/modules/javaapp/target/classes"
                       internalPath="/"
                       webAppMount="/WEB-INF/classes" />

    </Resources>

</Context>


And this

<?xml version="1.0" encoding="UTF-8"?>
<Context path="/webapp"  >   

    <Resources>


  <JarResources className="org.apache.catalina.webresources.JarResourceSet"
                      
base="D:/PROYECTOS/modules/javaapp/target/javaapp-1.0-SNAPSHOT.jar"
                       internalPath="/"
                       webAppMount="/WEB-INF/lib" />

    </Resources>

</Context>


I'm attaching the projects, all you have to do is change the base attribute of
the Resources
